Linear Technology LT3796

The LT3796/LT3796-1 feature a programmable threshold output current sense amplifier with rail-to-rail common mode range. The PWM input provides LED dimming ratios of up to 3000:1. The LT3796-1 is optimized for a second output current regulation loop that can be enabled/disabled with a PMOS switch, either to drive a second LED string or to extend analog dimming range.
